Dual Safety Protection: Electrical tester features built-in overload protection and reverse connection protection. If the activation current exceeds 8A, the device will automatically trip and can be reset by restarting. Theres no need to worry about damaging the device due to reverse polarity when connecting the battery terminals, reducing the risk of operational errors and ensuring safe use even for beginners.
High-Definition Display: Electrical tester is equipped with a 1.8 -inch TFT color screen that clearly displays key data such as voltage, resistance, frequency, and duty cycle, while also supporting real-time reading of maximum/minimum values. It includes both a buzzer and dual-color red/green LED indicatorsfor example, the red LED lights up and the buzzer beeps when the positive terminal is detected, and a continuous beep with a red LED indicates circuit continuity. An LED light can also be turned on for visibility in dark environments, making testing status instantly recognizable.
User-Friendly Operation Design: The toggle switch supports single-click to switch interfaces/enter tests, double-click to lock the current display (for easy data comparison), and long-press to rotate the screen 180° (adapting to different testing angles). Before resistance testing, a "Do not test under power" prompt appears to guide proper operation. The device supports 12 language options, catering to users from different regions worldwide, with a low learning curve and quick mastery.
Wide Voltage Compatibility: The input voltage range is 8V~32V, with a testing voltage range of 0V~80V and an operating current of only 80mA. It is compatible with both 12V household cars and 24V trucks or construction machinery, making it suitable for a wide range of vehicles. The core components are made of high-quality materials and undergo rigorous performance testing, ensuring stable operation in common complex automotive repair environments such as high/low temperatures and vibrations, with a long service life.
